This is an EXCELLENT design

This is an EXCELLENT design idea but the body is a problem. It should be one piece the way it prints with the slight bevel causes structural weakness. If you print it the wrong way (hook body up) it completely fails if you print it face down the heat of the extruder pushes the independent bodies together and makes it strong enough.
